To a, whom it may concern:

Be it known that I, ALBIN OESTERREIOH, a

, citizen of the Empire of Germany, and a resident of'Hanover, Germany, have invented a certain new and useful Improvement in Machines for Making Necksfor Paper Boxes, of

which the following is a specification.

My invention relates to'machines for making paper boxes, and more particularly relates to improvements in machines for forming and fixing the neck-pieces for cylindrical or polygonal paperboxes.

My invention is furthermore an improvement upon my former invention embodied in my Patent No; 815,626, dated March 20,

. 1906, granted on my application, Serial No.

82,669, filed November 18,1901.

My invention has for its object to provide a machine which will carry out the process described in my PatentNo. 815,858, dated v March 20, 1906, grantedon my application,

Serial No. 210,288, filed May 28, 1904, in the manufacture of the necks orbodies of paper tact with the neck or body. Fig. 2 is a'simi-' lar view showing the pressure-roller in contact with the neck or body and" the edge of the pa er covering turned over the edge of the ho y-blank. Fig. 2.? is a transverse section thereof, taken on the line 2 2 of Fig. 2, showing the pressureroller supported as illustrated in my patents hereinbefore re ferred to. Fig. 3 is a similar ,view'to Figs. 1 and 2, showing the pressure-roller out of contact with the neck or body and. the edge of the paper covering turned over the edge of the body-blank and within the'neck piece. or body ready to be shoved ofl from the mandrel. Fig. 3 is a transverse section thereof,

taken on the line 3 3 of Fig. 3.

1 is a sliding and reciprocating mandrel having a reduced part 2. The reduced part 2 is free to rotate and to slide axially m a fixed bearing 3, which is fitted to. a support 4:. 5 is a fixed sleeve also fitted in the support 4 against the inner endof the. bearing 3.

.upon the mandrel 1, together with a The outer end of the mandrel is formed with a circumferential groove 6. I

7 is the body ofthe neck wound or coiledpaper covering 8.

9 is a reciprocating pressure-roller, which takes the place of the pressure-wheel 28 and is mounted u on a" lever 29, shown in mypatents herein before referred to. This pressure-roller 9 is therefore capable of being brought into contact with the outer surface of the neck. 10 is a flange upon the-roller 9, ada ted to enter the circumferential groovcfi.

e mechanism for advancing the body- 1 blank and paper covering of the neck and pasting the pa er-co-vering strip and feeding strip is shown in my patents hereinbefore mentioned. I

Q and cutting t e body-blank and covering- The mandrel l is given motion in rotation andaxially by the same mechanism as in said patents, and the pressure-collar 9 is reciprocated as in said patents, and means for gri ping and holding the incomin end of the b0 y-strip maybe employed,su'c asshown in said patents; For this reason I have not shown the operating mechanism in this application- As a matter of fact, in the manufactureof paper boxes of this description a machine is made like the machine shown in theformer patents referred to in this application. This machine is constructed to make the boxbody, tops, and bottoms.

these nec what is done is to remove artsof said machine and insert the specia de-' vices herein shown and-described.

'The circumferential groove 6 is-cut near the end of the mandrel 1 and is so positioned that the edge of the inner wall will. lie in a plane with the edge of the body over which the covering-stri' is to be turned. The width and. dept of this circumferential The necks are separatelymmade' and inserted, and to makev groove is such as to freely permit the inturning of the aper covering, as hereinafter described. he end of the .sleeve 5 is so positioned as to permit the winding of the bodyblank onto the mandrel 1 in the position shown in the drawings. A

I will now describe the operation of my invention. A body-blank 7 and a coveringstrip 8, coated with paste, are fed in. The mandrel 1 is given motion in rotation. The

same time the the body-blank 7 and into I clearl tact and the mandrel 1 is moved axial? in no his sleeve 5 to come invcontact with the "edge of said sleeve,

the b0 y-blank 7.

roller 9 is moved down upon the incoming material and presses the body-blank and covering-str'p firing onto the mandrel. At the ange 10 turns the rojectin 1 edge of the covering-strip 8 over t e edge 0 the groove 6, as shown in Fig. 2. This movement competed, the roller 9 is moved out of conthe direction of the arrow in Fig. 3.

causes the edge of the neck adjacent to the and as the axial movement is continued the inturned edge of the coveringstrip 8 will come in contact with the outer wal of the groove 6' and will be turned in and firmly asted down u on the inner surface of urther axial movement of 'themandrel 1 will withdraw it from Within the body-blank 7 and the finished neck will be free to drop out of the machine. It is to be noted that while the body-blank 7 is wound snugly uponthe mandrel and given the proper diameter the edge is positioned I or put in plane at ri ht angles to its axis by contact .with the en of the sleeve 5; Thus .ers,- with which they jected end, a sleeve while held to -position the covering-strip is folded in and surface of the ody, as descri ed, and thus the cylinder 01'' polyggnal section is fixed. The importance oft 's feature will be at once understood, since it is necessary that asted down 11 on the inner the necks make a close fit with the box-covhave telescopic connection. Itwill be evident that I-am able to accomplish he same end by reciprocating the sleeve 5 instead of the mandrel;

- Having thus described my inventiomwhat Iclaim is A v j a In a machine for making necks for pa er boxes a-rotatin and axially-sliding man elhaving circum erential groove in its fitting over the man el',

a pressure-rollerhavmg a flange and adapted to work in conjunction with themandreland the circumferential groove,

and means for reciprocating the pressure-roller.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
